Package: gdm3 Version: 3.13.92-1 I have a Lenovo X1 Carbon Type 20A8 laptop with a OneLink Pro dock. I have two external monitors, one connected to the mini-DisplayPort on the laptop itself and another connected to the DVI port on the dock. Under Ubuntu 14.04, I am able to drive all 3 displays (laptop built-in display and the two external monitors) just fine.
Under Debian the behavior is quite weird: *If I have the dock plugged in before boot, all 3 screens are black once GDM launches into the login screen. *If I have the dock plugged in after boot and all 3 displays are enabled in the GNOME Display settings, then everything turns black, but I can see the mouse cursor moving around. *If I plug in one of the monitors to the mini-DisplayPort, disable the laptop built-in display, and THEN plug in the dock, I can drive the two external screens fine. Expected behavior: I should be able to drive all 3 displays just fine and unplug each external monitor and have it dynamically readjust. The Xorg log looked okay to my untrained eye. I am unsure of which logs to attach. Please let me know which ones you guys need to debug this and I will be happy to get it to you ASAP. I am using an up to date Debian testing with kernel 3.16-2-amd64 and libc6 2.19-11 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
